Abstract

The invention provides a process for preparing a sulphur cement product comprising the following steps: (a) selectively oxidising hydrogen sulphide to elemental sulphur by contacting, in a reaction zone, a hydrogen sulphide containing feed gas and a molecular-oxygen containing gas with a particulate oxidation catalyst under selective oxidation conditions; (b) discharging a stream comprising liquid and/or solid elemental sulphur and particulate oxidation catalyst from the reaction zone; (c) admixing the stream comprising elemental sulphur and particulate oxidation catalyst with at least any one of elemental sulphur, a sulphur cement filler, a sulphur cement modifier, or aggregate at a temperature at which sulphur is molten; (d) solidifying the mixture obtained in step (c) by cooling it to a temperature below the melting temperature of sulphur to obtain the sulphur cement product. The invention further provides the use of a stream comprising elemental sulphur and particulate oxidation catalyst for preparing a sulphur cement product, which stream is obtained in selective oxidation step (a) of such process.
